Application led April 22, 1921. SrialNo. 463,487.

To all 'whom fz't may con/cem.:

Be it known that I, GEORGE J. PUTH, a citizen of the United States, residing at Appleton, in the county of Outagamie and State of Wisconsin, have invented certain new and useful Improvements in Snowplows, of which the following is a specificatiom This inventionrelates to snowplows and has for its principal object to provide a plow of this nature which is provided with means whereby thesnow may be eciently pushed to one side.

Another object of the invention is to provide'y a snowplow with heating means so as to prevent the snow from sticking thereto.

A still further object 4of the invention is to generally improve upon .snowplows of this character by providing a mechanism which will be of extremely simple, durable and inexpensive'construction, one which is ecient and reliable in operation and well adapted to the purpose for which itis designed.

With these and numerous other objects in view, the invention resides in certain novel features of construction and the combination and arrangement of parts as will be hereinafterl fully described and claimed.

Figure 1 is a side elevation of a vehicle showing the snowplow attached thereto,

Figure 2 is a top plan view of a vehicle showing the snowplow attached thereto,

Figure 3 is a front elevational view of the snowplow, and

Figure 4 is a side elevational viewthereof,

Referring to the drawing in detail it will be seen that 1 designates a motor vehicle of any preferred construction to the forward end of which is attached the snowplow 2. This snowplow 2 includes the body portion v 3 and the -extensions 4. This extension is disposed atan obtuse angle to the body portion 3 as is shown to advantage in Figure 2. The4 body 3 and extension 4 are curved throughout their height so as to form scooped-shaped members. The body portion 3 is provided with a rear wall 4 so as to form the compartment 5. The exhaust pipe 6 is in communication with the compartment 5 and will lead from the internal combustion en ne on the motor vehicle 1. This exhaust pipe 6 mayllead from any engine which it is desired to place upon the vehicle 1 so that the burnt gases or exhausted steam may be deliveredto the compartment 5 so as to heat the inner wall 7 of the body 3 thereby preventing the snow from sticking or freezing thereto. The body portion 3 of the plow 2 is attached to the provided with the extensions 12 and 12" shown in Figure 1. A pair of worms 13 are suitably journalled in brackets 14 so as to extend vertically and the threads of thesev worms13 are engaged by the extensions f11 and 12. Each worm 13 is provided with abeveled gear 15 in mesh with beveled gears 16 carried on shafts 17. Beveled gears 18 are suitably mounted on the inner ends of these shafts 17 and are in mesh with a beveled gear 19 keyed to the shaft 20 which is operable by thewheel 21. By proper rotation of wheel 21 it will be seen that the rods or extensions 11 and 12 may be turned on the axle 10 thereby raising or lowering the plow 2. The extension 12 is adapted to engage the vehicle 1 when the plow isin a raised position and the extension 12 engaged with the bottommost thread of the worm 13; An arm 23 is suitably attached to the arm 9 and. extends through the extension 4 and is provided at its end with the journal 24 for receiving the shaft 25r which extends parallel with the extension 4. A suitable fan or propeller 26 is fixed to the end of the shaft 25 adjacent the body 3 and suitable means are provided for the rotation of this propeller 26 so as to draw the snow from the ody 3 into the extension 4 and force it to the side of the road. In this particular illustration of my invention I' have disclosed a beveled gear 27 suitably keyed to the shaft 25 intermediate its ends which beveled ar is in mesh with beveled gear 28 fixe on shaft 29 at the other end of which y'is provided a gear`30 in mesh with gear 31 which is rotated by any suitable means such as through the gearing 32'driven by thel motor 33.

From the foregoing description, taken in connection with the accompanying drawings, the construction and operation of the snowplow will be readily understood without a more extended explanation. As numerous changes in form, proportion, and in 5 the minor details of construction may be resorted to without departing from the spirit of this invention I do not wish to belimited to lthe constructionherein shown and de-` scribed other than as claimed. i

Having thsdescribed my invention what ll claim as new is In combination, a vehicle, a plow, means for pivotally attaching the plow to the Ve- Y hicle, a bai-attached at one end toN the plow meme? bar, means for turning the worm so as to raise and lower the plow, and an extension formed on the bar for engagement with the vehicle so as to liinit the upward movement of the plow.

lin testimony whereof lf ax my signature in presence of two witnesses.

GEORGE J. PUTH.
